All you need to know ahead of tonight's crucial gameThe Lions entertain Birmingham City at The Den on Tuesday night (7.45pm) knowing that a win could move them to within two points of Lee Clark's men, who sit 20th in the Championship.
Saturday's narrow defeat at Elland meant Ian Holloway's side remained in the drop zone but a victory over The Blues could see Millwall climb out of the bottom three providing Charlton Athletic, in 21st, don't win away to Nottingham Forest.
Millwall will once again be without Shaun Williams, who serves the second match of a two-game suspension, but striker Steve Morison is available after sitting out Saturday's loss at parent club Leeds.
Nicky Bailey (back) and Jermaine Easter (thigh) are likely to be missing once more, while Danny Shittu (achilles) remains a long-term absentee.
Birmingham boss Lee Clark will be without midfielder Emyr Huws (hip), while striker Lee Novak is a doubt after picking up an injury in the club's defeat at home to Reading on Saturday.
Former Lions loanee Brian Howard is pushing for a start after recovering from an ankle problem.
Saturday's 2-1 loss against Leeds means Millwall have just one win in their last 11 games. The Lions have gone five games without a victory at The Den, a run which stretches back to January's 1-0 win over Ipswich Town.
Birmingham, who sit five points ahead of Millwall in the Championship table, have lost four of their last five games, with their only point this month coming from a 3-3 draw with Burnley.
They have won seven games on their travels so far, the most of any side outside the Championship's top eight.
The Lions' recent record against Birmingham doesn't make for good reading with The Blues unbeaten in the last 13 games between the two sides. Of those 13 they have won eight, including October's 4-0 victory at St Andrew's.
Birmingham have won five of their last seven visits to The Den. Millwall's last home victory against Birmingham coming in April 1996.
